5. OperatingInstructions

5.1AdaptorConguration

•  The tester can be congured to t onto

a header tank or radiator when used

with a radiator cap/header tank

adaptor (not supplied). Fig.1 shows the

Combustion Gas Detector Kit being

used in conjunction with the Draper

Expert Radiator Pressure Test Kit

(Stock No.14455 – sold separately).

When the tube on the lower chamber

(4) is inserted into the brass connector

(5) ensure that the brass ring at the top

of the connector is tightened down so

that it grips the tube. The brass

connector will be a push t onto the

radiator or header tank adaptor.

Push down until it clicks into place.

To release, pull the ring at the bottom

of the brass connector upwards.

•  Fill the upper chamber (3) with test

uid to the dotted line.

•  Fit the cap (2) onto the upper chamber

and then x the rubber bulb (1) onto

the top of the cap.

•  Turn on the vehicle engine and wait for

steam to enter the lower chamber.

•  When the steam is visible in the lower

chamber, pump the rubber bulb

several times to draw steam into the

upper chamber. If the uid turns

yellow this indicates the presence of

CO

2

in the coolant and thus possible

damage to cylinder head gasket or

cracked head.

•  Alternatively the tester can be used

without the bulb attached. In this

conguration the steam will

automatically pass into the upper

chamber. Take care to keep hands and

face away from any jet of steam being

expelled from the hole in the top of

the cap.

•  As soon as the test is complete turn o

the engine and allow the system to

cool. Before removing the tester from

the radiator or header tank, open the

tap on brass connector to allow any

remaining pressurised steam to

escape. Thick gloves must be worn

during this process and when the

tester and connector are removed from

the radiator.

•  Remove the upper chamber from the

lower chamber by twisting apart.

Pump the bulb several times to draw

fresh air into the chamber. When the

air mixes with the test uid it should

return to a blue colour and can be

retained for future use in spare bottle,

this uid can be used approx. 3 times.

5.2Hand-heldconeconguration

•  Where no adaptor is available a rubber

cone can be tted to the bottom of the

tester as shown in Fig.3. This allows

the tester to be held in place on a

header tank or radiator opening.

WARNING! Thick protective

gloves must be worn when using

the tester in this conguration to

protect the operator from any

escaping steam. Great care

should be taken when placing

the adaptor over the radiator or

header tank opening and also

when removing it.

•  Fill the upper chamber (3) with test

uid up to the dotted line.

•  Remove the radiator or header tank

cap. Turn on the vehicle engine and

wait for steam to appear. Place the

tester onto the radiator or header tank

opening and hold it down and steady

so that it makes an eective seal

against the opening.

•  As soon as the steam appears in the

lower chamber (4) pump the bulb (1) to

draw the steam into the upper

chamber. If the uid turns yellow this

indicates the presence of CO

2

in the

coolant and thus possible damage to

cylinder head gasket or cracked head.

•  As soon as the test is complete remove

the tester from the radiator or header

tank (and turn the engine o).

Where there is no more steam

emanating from the radiator or

header tank, replace the cap.

•  Remove the upper chamber from the

lower chamber by twisting apart.

Pump the bulb several times to draw

fresh air into the chamber. When the

air mixes with the test uid it should

return to a blue colour and can be

retained for future use.
